Using Trac unaltered TICKET_VIEW permission is required for this, and
core code doesn't differentiate between view of current ticket
properties in the colored box on top of the ticket page and presentation
of historic values - the change history.
However, I think Trac is still good to do what you want with a little
development work, as there's no ready-made plugin right now AFAIK.
Some pointers for minimum requirement:
* implementation of interfaces of Trac's component architecture [1] for
* IPermissionRequestor [2] to add another action/permission like
TICKET_HISTORY_VIEW
* ITemplateStreamFilter [3] to intercept any processing of a request
for 'ticket.html' template and alter the content depending on
permission found in req.perm permission cache for that request
* use XPATH expression to pick the Genshi template portion containing
ticket history from the stream [4]
roughly like so:
from genshi.filters.transform import Transformer
from trac.core import Component, implements
from trac.perm import IPermissionRequestor
from trac.web.api import ITemplateStreamFilter
class TicketChangeViewFilterPlugin(Component):
implements(IPermissionRequestor, ITemplateStreamFilter)
tkt_chg_view = 'TICKET_HISTORY_VIEW'
# IPermissionRequestor method
def get_permission_actions(self):
return [tkt_chg_view]
# ITemplateStreamFilter method
def filter_stream(self, req, method, filename, stream, data):
if filename == 'ticket.html' and not tkt_chg_view in req.perm:
xpath_match = '//div[@id="changelog"]'
filter = Transformer(xpath_match)
stream |= filter.remove()
return stream
Well, I guess that's it; untested, but most needed parts to make it work
for you.
Sincerely,
